[PD] firmata sporadic at enabling analog ins?

If you are on GNU/Linux or Mac OS X and using an Arduino Diecimila,  
then the Arduino will reset whenever you connect to it, i.e. send  
[open 2( message.  It needs to then boot up again.

Once the Arduino has booted up, it'll report its version.  You can  
get this version message from [arduino]'s 2nd outlet.  So you could  
[route version] and use that to send the messages.  That will  
guarantee the arduino is ready to listen to your messages.
